Procedure

A suspension of 1.45 g (4.8 mmol) of 10-chloranthracene-1,9-dicarboxylic acid in 50 ml of acetic anhydride was heated under reflux for 4 hours and then cooled to room temperature. The yellow precipitate that formed was collected by filtration, washed with cold methanol and dried to give 0.83 g (61%) of the title compound, m.p. 269°-271° C.
